Before this patch, we used tlbiel, if we ever ran only on this core.
That was mostly derived from the nohash usage of the same. But the
ISA 3.0 clarifies tlbiel such that

"All TLB entries that have all of the following properties are made
invalid on the thread executing the tlbiel instruction"

Hence use tlbiel, if we only ever ran on just the current cpu.
